Patented Jan. 10, 1950 UNITED srarss PATENT POLYPOINTED WRITINGRETRACTABLE OFFlCE 1 Claim.

The present invention relates to improvements in poly-pointed writingutensils, such as multicolor pens and pencils and, more specifically, toan improvement over vtllamulti-color writing utensils described in myco-pending patent application. v

By my co-pending patent application I have discussed multi-color pensand pencils v Whose pointed extremities or writing nibs are stationary.It is sometimes desired to cover the writing nibs while the device isnot in use. While this can be accomplished by means ofa removable cap, Iprefer to use an outer barrel into which all the writing nibs can beretracted simultaneously. Multi-color pencils, having for each color aseparate mechanical element which may be projected from the pencil andexposed for writing while similar elements for other` colors not in useremain concealed, are Well known. They have, however, the disadvantagethat said separately projectable and retractable elements necessarilymust be of such small dimensions that they can be damaged easily and aresubjected to excessivey of a writing utensil of the character describedl which is simple in construction and use, handy, light in weight and ofa comparatively small size, but sturdy, durable and Well adapted towithstand the rough usage to which devices of this type frequently aresubjected.

With the foregoing and other objects in View which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the claim, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

In the accompanying drawings the preferred forms of the invention havebeen shown.

In said drawings:

Figure 1 is a top plan view of a two-polo embodiment of my invention;

Fig. 2 is a top plan view oi a three-color embodiment of my invention;

Fig. 3 is a top plan view of a four-color embodiment of my invention;

Fig. 4 is a longitudinal sectional view of a preferred embodiment of myinvention; y

Fig. 5 is a cross-sectional View on the line 5-5 of Fig. 4;

Fig. 6 is a cross-sectional View on the line 6 of Fig. 4;

Fig. '7 is a fractional side view of a detail; and

Fig. 8 is a fractional longitudinal sectional View of a modication of myinvention.

In the drawing the numeral I denotes an outer barrel or stock on whoselower end portion is slidable a cap 2 to which is secured a clip 4. Ashaft 3 extending into the outer barrel I is secured to the cap 2 bymeans ci a screw 5' which has a knob-shaped head 5. A tubular member Ewhich is provided with a curved slot I0, and a threaded head portion 'Iis secured by the latter to an internally threaded portion of the outerbarrel I. An inner barrel 8 has an internally threaded collar portion 9extended from its bottom, and the upper extremity of the shaft 3 isscrewed into the collar portion 9. A pin II extends laterally from theshaft 3 and engages the slot I i), and a spring i2 is interposed betweenthe pin II and an annular shoulder I3 which is welded or otherwisesecured to7 or formed as a unit with the outer barrel I. Thus by turningthe cap 2 relative to the outer barrel in one direction, the latter isslid over the inner barrel through the action of the spring I2 as isindicated in dash-and-dotted lines in Fig. 4, While by turning the cap 2in the opposite direction relative to the barrel I, the parts 3 and 8are brought into a position relative to the barrel I as is shown in fulllines in Fig. 4.

A plurality of internally threaded tubular members I4 are extended intothe uper portion of the inner barrel 8 and are rotatable therein. Eachmember I4 has an annular groove ZI. The grooves 2i are equally spacedfrom the extremities of the members I 4; and a cross-pin 20, which isextended through and secured to the inner barrel 8 engages the grooves 2I, so that the members I4 cannot vbe moved axially relative to the innerbarrel 8. Leads I5 oi diiierent colors are extended from above into thethreaded bores I'I of the members I4. A spindle I5 is screwed into eachbore I'I and is provided with a head I8 that has a peripheral verticalgroove 3d (Fig. 6). A rail I9, which is cross-shaped in cross-section inthe instance of the four-color pencil shown, but which may be Y-shapedin the case of a three-color pencil, or rectangular in cross-section inthe case of a two-color pencil, is secured to the bottom of the innerbarrel 8 and is in slidable engagement with the grooves 30 of the headsI 8 of the spindles I8 so that the latter cannot be revolved. The outerside of that portion of each member I4 which projects beyond the innerbarrel 8 is knurled for facilitating a turning of the members I4. Byturning the members I4, the spindles I6 are screwed more or less intothe members I4, so that the leads I5 can be pushed toward the upperextremities of the members I4.

In the case of a multi-color pen (Fig. 8) the same outer barrel havingan internal annular shoulder I3 and the same shaft 3 etc. can be used asin the oase of the modification of Figs. 4 to 7.

The inner barrel 22 has a collar 23 which is similar to the collar 9inFig. 4, but to its upper extremity is secured, by screwing or the like,a hollow tip 24. A plurality of cartridges 25, each of which terminatesinto a writing nib 2E, have their base portions extended into the tip24` A tubular lbody 21 is secured to the base portion of each cartridge25 and is extended into the inner barrel 22. The parts 25 and 2l containwriting fluids, such as ink, of different colors.

Since certain changes may be made in the above article and diiferentembodiments of the invention could be made without departing from thescope thereof, it is intended that all matter contained in the abovedescription or shown in the accompanying drawing shall be interpreted asillustrative and not in a limiting sense.

It is also to be understood that the following claims are intended tocover all of the generic and specific features of the invention hereindescribed, and all statements of the scope of the tremity a head whoseperiphery is grooved, an

upright rail being secured to the bottom of said inner barrel and beingin slidable engagement with a peripheral groove in the head of eachspindle, an outer barrel in which said inner barrel is slidable, andmeans for moving said inner ybarrel relative to said outer barrel, leadsof different colors being slidably extended into said tubular members.
